hello and welcome to this tutorial on
graphing and calculus with a dream calc
scientific calculator green calc is a
fully-featured windows up which looks
and feels much like a real handheld it
supports pretty much everything you'd
expect from an Advanced calculator
including algebraic and our pian imports
and starts shift z-score point 9 8
equals 2.3 26
it also has a graphing capability as
greater plotting functions really
quickly it can do some other pretty neat
stuff as well as we'll see
so let's start by plotting an example
which will paste into the function input
box
before we go ahead
not this we need to make sure that the
angle mode is set correctly
we can control the x-axis with these
range parameters we can specify either
the number of points to plot of the plot
interval the y-axis is automatic
although we can force the range to start
from the origin
we can also plot two functions on the
same chart by designating second imports
as plot B and by dragging the cursor we
can zoom into a region of interest now
let's go back to our first function
input
we can see that as we move the cursor
over the plot the cursor coordinates are
displayed in the box on the bottom left
side of the window now we can fix the
current cursor position simply by single
clicking and as we move the cursor away
we find his position has been stored far
as
furthermore we can use the count button
on the bottom right to perform a variety
of numerical calculations including
differentiation and integration so let's
use it to determine the integral between
the range 1 and 6
8.1 a 348
we can also see that this result is
shown in the graph for Terraria as a
final demonstration let's copy the graph
and paste it into an external document
